NoSlow: Microbenchmarks for various array libraries

[ bsd3, development, profiling, program ] [ Propose Tags ]

NoSlow is a benchmark suite for several Haskell array libraries: standard lists, primitive sequential arrays from the DPH project, uvector, vector (primitive, storable and boxed arrays) and storablevector. At the moment, it implements a bunch of fairly random loop micro-kernels but will include many more benchmarks in the future.

In its present state, NoSlow cannot be used to reliably compare the performance of the benchmarked libraries. It can be quite helpful for identifying cases where a closer inspection of the generated code might be warranted, however.

The package builds two binaries.

noslow -u log
runs the benchmarks and writes the results to log
noslow-table log > table.html
outputs the results as a HTML table. It also supports the following options.
noslow-table log --type=Double
only outputs the results of Double benchmarks.
noslow-table --diff log1 log2
produces a table comparing the results from log1 and log2 (2 means the first run was 2x slower than the second; 0.5 means 2x faster).

NoSlow is described in more detail here:
